The bit about the name seems to be a complete hallucination / tokenization error. The project's docs say: "Forgejo (pronounced /forˈd͡ʒe.jo/ (hear an audio sample)) is inspired by forĝejo, the Esperanto word for forge." I would expect the rest of the AI summary to be similarly unreliable / hallucinated—I compared the test directories for both projects and they both seemed to have about the same amount of activity.

For all sorts of reasons, this will probably happen to the vast majority of LLM output copy-pastes here.

It's a bit like copy pasting a search result link (anyone can do the search for themselves). LLM outputs don't provide the insight people are looking for on HN. They are unreliable. They sound boring. They may sound like ads for the LLM providers. There's probably someone out there actually knowing the thing and able to answer. There's usually a better way of finding out stuff. For instance, if you want to learn about Forgejo, going to its website or its Wikipedia page will be far more straightforward and reliable.

You also stated that something that contains hallucinations is surprisingly decent, which can mislead people (who should strive to stay alert though).

Many people also just plain dislike generative AI.

You are not the first to whom it happens, and you'll probably not be the last.

At that point, I believe HN's guidelines should be updated to discourage posting LLM outputs in most contexts.
